A dental restoration or dental filling is a treatment to restore the function, integrity, and morphology of missing tooth structure resulting from caries or external trauma as well as to the replacement of such structure supported by dental implants.
Here are some common dental filling options :
- Composite resins, or tooth-colored fillings, are a mixture of glass or quartz filler that provide good durability and resistance to fracture in small- to midsize fillings that need to withstand moderate pressure from chewing. They can be used on either front or back teeth.
- Dental amalgam, sometimes described as “silver-colored” fillings, is made from a combination of metals that include mercury, silver, tin, and copper. Dental amalgam has been used for generations by dentists. Amalgam is very durable and more affordable than tooth-colored or gold fillings; however tooth-colored materials are more natural looking.
- Gold fillings, also called inlays or on-lays, are composed of an alloy of gold, copper and other metals. Gold has been used in dentistry for more than 1,000 years due to its durability; however, gold is more costly than amalgam and not natural looking like tooth-colored fillings.
Causes of Tooth Pain After Fillings
Fillings are used to replace the decayed area of the tooth, reducing the pain associated with the cavity itself. But tooth pain after filling a tooth is not unusual. Some common reasons for tooth pain after a filling include:
- Tooth sensitivity: A tooth that has just had a filling placed will be more sensitive to hot foods and cold foods, air temperature, and the pressure of biting. This type of tooth pain after filling a cavity should resolve within a few weeks. If not, contact your dentist.
- Cracked or loose tooth fillings: Tooth pain after filling a cavity can occur if the filling is not fitting properly to the tooth, or if it develops cracks. If you suspect that your tooth pain is caused by a cracked or ill-fitting filling, contact your dentist.
- Allergic reaction to tooth fillings: Some people have allergic reactions to the material used for their fillings, such as silver. To help avoid tooth pain after filling a cavity, be sure to tell your dentist about any allergies when discussing your filling choices.
